Healthy, vigorous, and fit to successfully do his duties as president of the United States. This is how President Joe Biden's doctor described the president's health condition last year before being sworn in office.

Kevin O'Connor was Biden's physician and primary care doctor when he served as vice president. He was also the one who prepared Biden's medical report before taking oath as president, NPR reported.

However, a former White House physician and now a representative for Texas' 13th Congressional District has an entirely different opinion on Biden's health.

Ronny Jackson served as a physician to former presidents. His questions regarding Biden's health came after the president's triple fall on Air Force One's stairs, Washington Examiner reported.

"I served as White House physician under THREE Presidents. I've seen what it takes physically AND mentally to do the job. I can tell you right now that the way Biden is hiding from the public is a MAJOR red flag. Something's not right!," Jackson tweeted on Sunday.

Biden stumbled three times while boarding the presidential plane departing for his Atlanta visit on Friday. White House Communications Director Kate Bedingfield said the president was fine, adding that it was just a misstep on the stairs.

The president's health was also put under the spotlight after the president accidentally called Vice President Kamala Harris as "President Harris," raising questions about his mental shrewdness, New Zealand Herald reported.

Joe Biden had also accidentally called his wife Jill as his sister during the election campaign. A senior politician in Russia alleged Biden of having dementia on Thursday. The president replied by calling Vladimir Putin a "killer."

Joe Biden's Health

Under the medical report that O'Connor released before he won the election, Joe Biden has an irregular heartbeat, known as nonvalvular atrial fibrillation.

The report noted that Biden is not required to take any medication or other treatment for this heart condition. However, he does take a blood thinner as the condition can also increase blood clots' risk. It added that the president has other conditions such as hyperlipidemia, gastroesophageal reflux, and seasonal allergies.

Biden was also required to wear a protective boot for several weeks late last year after x-rays revealed a "hairline fracture" in his foot, The Sun reported.

The president's most serious health condition was in 1988 when a bulging blood vessel in his brain burst. This was repaired surgically, and doctors at the time discovered another bulging blood vessel, which was also treated.

In 2003, the president's gall bladder was removed, and he had multiple physical therapy surgeries and treatments for various orthopedic injuries and sports medicine.

It was also reported that Joe Biden was treated for benign swelling of his prostate gland. His doctor earlier said that he does not use tobacco products or drink any alcohol, and he works out at least five days weekly.

Biden said he uses a Peloton bike to keep fit and often tries to jog. So far, Joe Biden is the oldest sitting president in U.S. history at the age of 78.
